Patent attributes
A dual-clutch transmission comprising clutches with input sides coupled to an input shaft and output sides respectively coupled to two transmission input shafts. Toothed idler gearwheels are mounted to rotate on countershafts while toothed fixed gearwheels are connected to the first and the second transmission input shafts and engage with the idler gearwheels. Coupling devices are provided for connecting the idler gearwheels to the countershaft, and drive output gearwheels are fixed to the countershafts and couple an output shaft, while a shifting element couples the input shafts such that eight forward gears and at least one reverse gear can be engaged. Four wheel planes are arranged in the transmission such that at least one winding gear can be engaged by the shifting element.
